ABSTRACT:
Sulfuryl chloride is reacted in the liquid phase with an organic reactant which is a ketone or aromatic alcohol unsubstituted on both ortho carbons in the presence of a moderator selected from the group consisting of aliphatic alcohols of 1-3 carbons and aliphatic ethers of 2-6 carbons, with sufficient moderator being present to selectively produce a product substantially free of compounds with more than one chlorine atom per carbonyl or aromatic hydroxy. The products, such as monochloroacetone, monochlorocyclohexanone, monochlorophenol and 2,2-bis(3-chloro-4-hydroxyphenyl)propane, are useful as chemical intermediates and as monomers for flame retardant polymers.
